The self-warming or self-heating cosmetic compositions of the present invention comprise: (i) from about 0.1 to about 99% by weight of an anhydrous skin care preparation; and (ii) from about 0.01 to about 99% by weight of a heating agent selected from polyvinyl amine, polyalkyleneamine or polyalkyleneimine.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to self-warming or self-heating cosmeticcompositions that are based upon the reaction of a polyvinyl amine or apolyalkyleneimines and water to provide the warmth sensation. Theself-warming or self-heating cosmetic and dermatological composition isactivated with moisture.

2. Description of the Related Art

Heat-producing cosmetic compositions produce a very pleasant sensation.These formulations are friendlier than the cold traditional productsapplied to the skin. Conventional systems developed for generatingwarmth have been described.

EP-A-27730 describes a cosmetic composition which may for example be ahair treatment or hand treatment composition and which generates heat oncontact with water. In this application, heat generation is alleged tobe provided by the presence of polyethylene oxides, polypropyleneoxides, and derivatives thereof, and a 2 to 9 carbon atom alkalineglycol. It has been found that the formulation of compositions based onor containing significant amounts of propylene glycol needs to be verycarefully controlled, since a number of propylene glycol basedcompositions suffer from product separation on storage.

EP-A-586929 describes a two pack system which generates heat on theaddition of water, and produces a physiologically compatible salt thatgenerates heat on mixture with water. Also contributing to the heat feltby the user on hydration of the product is the heat of hydration ofpolyethylene glycol.

GB-A-1357000 describes a topical cosmetic composition comprising ananhydrous polyol and an absorbent particulate filler material. Suitablepolyols are said to include propylene glycol, glycerol, 1,3 butyleneglycol, and polyethylene glycols having an average molecular weight offrom 2 to 300 and from 1000 to 6000.

U.S. Pat. No. 6,287,580 discloses a self-warming cosmetic compositionwhich delivers skin conditioning agents and is based upon a redox systemof iron powder and a catalyst such as charcoal to provide the warmth.The system is activated with moisture and air. The self-warmingcomposition is comprised of: (i) from about 0.1 to about 30% by weightof silicone oil or carboxylic ester as a skin conditioning agent; and(ii) from about 1 to about 95% by weight of a redox system based uponiron powder and a high surface area catalyst which is charcoal.

U.S. Pat. No. 4,839,081 discloses a two-stage chemically heated liquidsoap composition dispensed as a cleansing composition for the face andhands. The heating is derived from a novel double reductant and singleoxidant redox system. Preferred active parts of the redox system arehydrogen peroxide and a combination of sodium sulfite and ascorbic acidwith a suitable catalyst. The other components of the composition maychange in accordance with the desired cleansing properties of thecomposition.

U.S. Pat. No. 4,439,416 discloses a cosmetic preparation which iseffective for providing a cosmetic product that is heated at time of useby the heat of an exothermic reaction, and a process for carrying outsuch heating. The self-heating cosmetic preparation is composed of atleast two discrete parts particularly suitable for providing a heatedcosmetic product at time of use has one part comprising a hydride and asecond part comprising a reducible material adapted to reactexothermically with said hydride on contact therewith, and a cosmeticbase in which one of said parts is incorporated, whereby at time of usethe parts combine and interact exothermically to issue as self-heatedcosmetic preparation.

U.S. Pat. No. 4,110,426 describes nonaqueous compositions, especiallycosmetic preparations such as shaving creams which are renderedself-heating by including therein a compound containing at least oneboron-oxygen-boron linkage, such as triethoxyboroxine, which reactsexothermically with water or other protic material.

U.S. Pat. No. 4,088,751 discloses a packaged self-heating cosmetic, suchas a shaving cream, hand lotion, depilatory, facial, or a shampoo,including separate exothermically reactive reductant material, such as2-thio-4-oxypyrimidine or thiohydantoin or derivatives thereof, and anoxidant, which reacts with the reductant, generating heat. Means areprovided for dispensing the packaged reductant and oxidant from separatezones and bringing them into contact with each other so that they reactand heat a pressurized shaving cream or other cosmetic product which arecontacted by the exothermic reaction mixture. The reducing agentemployed is preferably 2-thio-4-oxypyrimidine or its tautomer,2-mercapto-4-hydroxypyrimidine, or alkyl-substituted derivative thereof,and the oxidizing agent is preferably aqueous hydrogen peroxide.

U.S. Pat. No. 3,250,680 relates to the use of finely divided solidadsorbent materials which are capable of exothermically reacting withwater. Illustrative of these materials are silica gel, activated aluminaand synthetic zeolites. U.S. Pat. No. 4,626,550 relates to similarheating systems with improved versions of zeolite based on the presenceof potassium ions as replacement for some of the sodium ions. WO93/08793 describes other exothermic agents which are reactive withwater. The agents include kaolin, Fuller's Earth, china clay andbentonite.

U.S. Pat. No. 6,455,058 describes a composition and method for scalptreatment. The hair and scalp treatment contains an anti-dandruff agentsuch as salicylic acid, polyethylenimine (PEI) and an amphotericsurfactant. The anti-dandruff agent and PEI are incorporated in oneformula to have a dual function of both hair and scalp treatments. PEIprovides an effective hair conditioning ingredient. The composition isincorporated into either an aqueous or anhydrous solvent system. Theanhydrous formulas have self-heating action whenever they are applied onwet hair.

The self-warming or self-heating cosmetic compositions of the presentinvention comprise:

-   -   (i) from about 0.1 to about 99% by weight of an anhydrous skin        care preparation; and    -   (ii) from about 0.01 to about 99% by weight of a heating agent        selected from polyvinyl amine, polyalkyleneamine or        polyalkyleneimine.

DETAILED DESCRIPTION

Self-warming or self-heating cosmetic and dermatological preparations ofthis invention include various compositions intended for applicationtopically to the human body. Usually these are applied to the skin. Theyinclude face creams, body lotions, depilatories, tanning agents,antiperspirants, sun-screens, personal deodorants, shaving creams,makeup preparations, bath oils, facial treatments, astringents,after-shave lotions and many other related preparations.

The cosmetic preparations of this invention are made by simpleconventional methods. The various constituents of the cosmetic portionsof the preparations themselves can be combined in the normal manner andthen, depending on the nature of the cosmetic, can be further formulatedwith the polyvinyl amine or the polyalkyleneimines being employed.

The self-warming or self-heating cosmetic compositions of the presentinvention comprise:

-   -   (i) from about 0.1 to about 99% by weight of an anhydrous skin        care preparation; and    -   (ii) from about 0.01 to about 99% by weight of a heating agent        selected from polyvinyl amine, polyalkyleneamine or        polyalkyleneimine.        Polyvinyl Amines

A preferred composition according to the present invention contains fromabout 0.1% to about 50%, more preferably from about 0.1% to about 30% byweight, of one or more polyvinyl amines having the formula

wherein y is from about 3 to about 10,000, preferably from about 10 toabout 5,000, more preferably from about 20 to about 500. Polyvinylamines suitable for use in the present invention are available from BASFunder the name Lupasol®.

Optionally, one or more of the polyvinyl amine backbone —NH₂ unithydrogens can be substituted by an alkyleneoxy unit having the formula:—(R₁O)_(X)R₂wherein R₁ is C₂-C₄ alkylene; R₂ is hydrogen, C₁-C₄ alkyl, and mixturesthereof; and x is from 1 to 50. In one embodiment of the presentinvention the polyvinyl amine is reacted first with a substrate whichplaces a 2-propyleneoxy unit directly on the nitrogen followed byreaction of one or more moles of ethylene oxide to form a unit havingthe general formula:

wherein x has the value of from 1 to about 50. Substitutions such as theabove are represented by the abbreviated formula PO-EO-. However, morethan one propyleneoxy unit can be incorporated into the alkyleneoxysubstituent.Polyalkyleneimines

A preferred composition of the present invention comprises apolyalkyleneimine having the formula:

wherein the value of m is from 2 to about 700 and the value of n is from0 to about 350. Preferably the compounds of the present inventioncomprise polyamines having a ratio of m:n that is at least 1:1 but mayinclude linear polymers (n equal to 0) as well as a range as high as10:1, preferably the ratio is 2:1. When the ratio of m:n is 2:1, theratio of primary:secondary:tertary amine moieties of —RNH₂, —RNH, and—RN moieties, is 1:2:1. R can be C₂-C₈ alkylene, C₃-C₈ alkyl substitutedalkylene, and mixtures thereof. Preferably R is ethylene, 1,2-propylene,1,3-propylene, and mixtures thereof, and more preferably ethylene. Rradicals serve to connect the amine nitrogens of the backbone.

The polyamines of the present invention comprise homogeneous ornon-homogeneous polyamine backbones, preferably homogeneous backbones.For the purpose of the present invention the term “homogeneous polyaminebackbone” is defined as a polyamine backbone having R units that are thesame such as, all ethylene. However, this definition does not excludepolyamines that comprise other extraneous units comprising the polymerbackbone that are present due to an artifact of the chosen method ofchemical synthesis. For example, it is known to those skilled in the artthat ethanolamine may be used as an “initiator” in the synthesis ofpolyethyleneimines, therefore a sample of polyethyleneimine thatcomprises one hydroxyethyl moiety resulting from the polymerization“initiator” would be considered to comprise a homogeneous polyaminebackbone for the purposes of the present invention.

For the purposes of the present invention the term “non-homogeneouspolymer backbone” refers to polyamine backbones that are a composite ofone or more alkylene or substituted alkylene moieties, for example,ethylene and 1,2-propylene units taken together as R units.

Other suitable polyamines for use in the present invention are generallypolyalkyleneamines (PAAs), polyalkyleneimines (PAIs), preferablypolyethyleneamine (PEAs), or polyethyleneimines (PEIs).Polyethyleneimines suitable for use in the present invention areavailable from BASF under the trade name Lupasol® such as Lupasol™PR8515, having an average molecular weight of 1,800, Lupasol™ G20Waterfree; Lupasol™ FG, Lupasol™ P, Lupasol™ PR971L; Lupasol™ PL;Lupasol™ SKA, and other Lupasol® products. Ethoxylatedpolyethyleneimines suitable for use in the present invention areavailable from BASF under the name Lupasol™ SC®-61B. A commonpolyalkyleneamine (PAA) is tetrabutylenepentamine. PEAs can be obtainedby reactions involving ammonia and ethylene dichloride, followed byfractional distillation. The common PEAs obtained aretriethylenetetramine (TETA) and tetraethylenepentamine (TEPA). Above thepentamines, such as, the hexamines, heptamines, octamines and possiblynonamines, the cogenerically derived mixture does not appear to separateby distillation and can include other materials such as cyclic aminesand particularly piperazines.
